Hoists, Cranes and Derricks
Hazards of hoists include being struck by a heavy object, such as the boom or the load being moved. To reduce these hazards:
- Stay clear when a hoist is being used unless you are part of the procedure and, in which case, never stand under a load or boom with a suspended load.
- Wear personal protective equipment, such as head, foot, eye, and hand protection at all times.
- Assess the hoisting systems for structural soundness by inspecting regularly for problems with welds, rivets, chains, pulleys, lines, blocks, hooks, etc.
- Secure power blocks with a safety chain.
- Ensure that cranes in use are secured to the barge.
- Do not try to help lift a load being hoisted.
Areas that workers are able to access within the swing radius of a crane's superstructure present a hazard of being struck by, crushed, or pinched between the rotating superstructure and a stationary object. Employers should restrict those areas within the crane's swing radius from entry so as to prevent injury to workers.
Methods of marking the boundaries of the swing radius hazard area include control lines, warning lines, railings, and other similar barriers. Follow these safe practices to help prevent injuries due to crane operations:
- Ensure a method of communication is established between the crane operator and other workers.
- Do not move the crane and its superstructure until the "all clear" signal is given.
- If a worker will be working within the swing radius of the crane, the operator should physically lockout/tagout the crane.
- Make sure all workers are properly trained on the hazards associated with working around cranes.
